  • Brightness setting can react to environment or you can adjust from the 3 available brightness setting on the sight.


Burris Fastfire 2: Lens used here is not an ED glass. Yet, the clarity on low light is quite insane. But this is where the FF2 falls behind Fastfire 3 for the first time. This sight doesn’t have adjustable brightness. It automatically increases the brightness depending on what the sensor is feeding the sight. Which can result in some annoying moments. Other than that, the reticle is glass etched and it’s fine. It gets bright when needed.

Burris Fastfire 3: This sight has both 3 adjustable level of brightness and the same automatic sensor from Fastfire2. Together, they work like a charm. There is also windage and elevation adjustment present in this sight and they work. They are not there just for the shows.


Fastfire 2: Burris always uses good materials on their sight. Here it’s not different either. For housing Burris went with high-grade aluminum. As it’s such a small sight, going with aluminum made the more sense. Plastic or rubber this small will be fragile and can break easily. With aluminum, you don’t have such risk.

It can easily outlast your pistol if you are being careful around it. Some random drops of water won’t do anything to it. As this sight is completely waterproof.

Fastfire 3: Just like the 2, Fastfire 3 is also made out of aluminum. It’s a high-grade aluminum. There is no constructional or anodization flaw present on the sight. You can feel how premium it is once you held one in your hand.

It is made to last for a long time. If you don’t neglect this, it can very well outlast the warranty period.


Fastfire 2: While lacking behind the specs sheet by a lot, this sight certainly doesn’t lack behind performance that much. It still is underperforming compared to the Fastfire 3, but it’s not bad per say. It’s fairly accurate and can get the job done when you need it to. Reticle is bright enough to differentiate between target and non-target objects as well.

Fastfire 3: When it comes to performing on paper alone, this beats the FF2 by a long margin. Adjustable brightness is a huge plus for a sight of any size or shape. It is also highly accurate in short to semi mid-range. That’s a good enough range for short range hunting or tactical shooting. Specially on top of a pistol, it performs marvelously.


Fastfire 2: Total length of Fastfire 2 is 1.8inches. Not only this is lightweight, it’s also compact and small. It won’t seem too big on top of your pistol at all. A perfect size for pistol or rifles alike.

Fastfire 3: 3 outsizes Fastfire 2 by a small margin. It’s slightly longer than Fastfire 2. Total length of Fastfire 3 is 1.9inches. It’s also pretty small and compact. Difference is so small that it doesn’t even matter. It’s absurd how similar they are.


Fastfire II: Funnily enough, both FF2 and FF3 has the same exact weight. That’s right, FastFire 2 weighs at 1.5oz. Due to using the same material and mold, these two sights shares the same weight. That’s not rare among sights in the same family.

Fastfire III: As you can see, this sight also weighs at 1.5oz. A coincidence for sure, but welcome one. Weight balance is top notch as usual. None of the sight feels toe or head heavy. That’s a good thing for pistol owners. As this sight also supports pistol.
